Patent Details

Applicant:
Indian Institute of Technology (IIT) Roorkee 
Title:
Real time in-situ single optical density probe for biomass, substrate and product dynamics measurements in photobioreactor/bioreactor 
Inventor(s):
Sanjoy Ghosh and Shaliendra Singh Khichi 
Application type:
Applied - 2020-02-24 
Application Number:
202011007734 
Applied at:
India 
Entered by:
Indian Institute of Technology (IIT) Roorkee 
Abstract:
The present invention relates to a spectrophotometer/biomass monitor based on the modified Lambert-Beer law. In this modified Lambert-Beer model differential absorption is applied and coupled with the biomass, substrate and product kinetic equation of the microorganism. This probe measures biomass, substrate and product dynamics in photobioreactor/ fermentor in real time. In an embodiment, the data acquisition system (consists of control circuit loop and integrated circuit) is developed to capture the real time light dilution data as a function of microalgae growth, substrate and product profiling prediction. 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
